Work in progress

New asynchronous API

New AsyncSession (acquired from DaoSession.startAsyncSession()) provides most operations for DAOs, Queries, and transactions in a asynchronously variant
AsyncOperations are processed in order by a background thread
waitForCompletion methods for AsyncSession and AsyncOperations
AsyncOperationListener for asynchronous callback when operations complete
Asynchronous operations can be merged in single transactions (details follow)
Added raw SQL queries returning a Query object (LazyList support etc.)

Release History

V1.3.0 (2013-02-24): Multithreading robustness and refactoring (breaking changes!)

Reworked internal locking of insert/update/delete methods

Reworked queries to be used without locking, query instances are now bound to their owner thread (breaking change!)
Relations use the new lock-free query API
Query classes were moved into the new query subpackage (breaking change!)
Introduced Gradle build scripts for DaoCore and DaoGenerator projects
Maven artifacts are pushed to Maven Central starting with this version
Added two packages for classes used internally (identityscope and internal)
